IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 170,805, dated December7, 1875; application filed July 12, 1875.

peculiar construction and combination of the elastic rods and springs,as more full hereinafter set forth.

Figure 1 is a perspective view of a portion of my bed-bottom. Fig. 2 isa sectional elevation of one end of a rod and its spring, showing themanner of attachment thereto.

In the drawing, A represents around rod of any tough and resilient wood,havingascrewthread, a, cut on each end, which is screwed into the baseof a strong spiral spring, B, whose coils have the same pitch as thethread. The free end of the spring is turned to form a loop, 12, whichis slipped over a stud, 0, inserted in the upper edge of a bar, D,secured to the head or foot rail of a bedstead by means of thewood-screws d.

The rods should be short enough to put the springs under tension whenthe latter are hooked to the studs.

The slats being light and very elastic, conform to the outline of theoccupant of the bed, while the springs aiford an elastic supportto thebed, which yields to every motion of the sleeper.

What I claim as my invention is The combination, with the bars 0, havingvertical studs 0 on their tops, of the round Wooden rods A, having theirends threaded, and the spiral springs B, adapted to screw onto the endsof the said rods, and provided with loops b, when the several parts areconstructed and arranged substantially as described and shown.
